WILLIAM B. MILLER, OF PITTSBURGH, PENNSYLVANIA, ASSIGNOR TO COPPER-DIE HORSESHOE COMPANY, OF PITTSBURGH, PENNSYLVANIA, A CORPORATION OF PENNSYLVANIA.

APPARATUS FOR ELECTRICALLY FORMING TOES AND .HEELS 0N HORSESHOES.

Specification of Letters Patent.

Patented 'Sept. 22, 1914,

Application filed July 12, 1910. Serial No. 571,632.

State of Pennsylvania, have invented a new and useful Improvement in Apparatus for Electrically Forming' Toes and Heels on Horseshoes, of which improvement the following is a specification.

The present invention relates to an im-' proved device for electrically forming the heels and applying the calk members to the toes of horseshoes.

The object of my invention is to produce an apparatus by theuse' of which a complete shoe may be produced quickly.

Tothis purpose my invention .consists in subjecting the blank shoe and toe to be secured thereon to an electric current, the greatest resistance thereto occurring at the points of the shoe to be operated upon.

For a full understanding of the invention, reference is to-be had to the following description and accompanying drawing, in which Figure 1 is a side elevation of the apparatus, the outside plate or frame being removed; Fig. 2 is an elevation of the face of the operating table to which the shoe blank .is secured. Fig. 3 is a plan view partly in section; Fig. 4 is an elevation of the apparatus adjacent to theface of the operatlng table.

Referring to said drawings, 1 is a frame in which a shaft 2 is suitably journaled; 3 is a cam rigidly mounted on said shaft and adapted to be actuated or thrown into various positions by the lever i rigidl secured on one end of said shaft. The mner surface of said cam is provided with a number of grooves a which are adapted to engage with projections or serrations 6 upon the end of the die-bar 5 which is movably secured in bearings 6 secured to said frame.

The outer free end of said die-bar carries a die 7 which is adapted to engage with a toe 8 of the shoe 9, and the said toe is suitably heated as hereinafter specified, so that it may be thoroughly welded upon-the shoe by pressure exerted by said die through the medium of the bar andv the cam heretofore described.

A support or operating table 10 is arranged opposite one end of the casing 1,

and the shoe blank 9 is clamped against the inner face of'this support. For the purpose of holding the shoe blank in position a flap or clamping plate 11 is provided which is hinged to one side of the support 10 as indicated at 11, and has the swinging end thereof slotted at 11 for engagement with a latch member 24. By means of this clamping plate the shoe blank is held securely in a vertical position against the support 10, the curved end of the shoe blank projecting downwardly and being arranged directly opposite the end of the die-bar 5. This diebar 5 operates upon the toe of the shoe, while a cam 12 at the upper end of the support 10 is designed to operate upon the heel of the shoe. The said cam is mounted upon a rod or shaft 13, which is suitably insulated so that when the current is carried through the conductor 14, 15 and through the switch 16 and said shoe 9 to the ends of the blank, the said ends become suiiiciently heated as to enable the same to be turned at right angles to the blank by pressure exerted .by said cam 12. it is understood that the current is not conveyed to the ends of the blank as just described until after the toe or cork has been secured upon the shoe blank, as

shown in F ig, 1, upon the completion of .that the circuit just described, when broken by the withdrawal of the die-bar 5 as specifled, asses through the shoe as heretofore speci ed.

23 is a clip former which is pivotally mounted upon the shaft 25 which is secured to the die bar 5 upon the lower side thereof. The said clip former normally swings downwardly from said shaft, as shown in Fig. 1, but is capable of being swung into a horizontal position beneath the die bar 5, as shown in Fig. 4, so that the forward curved end j thereof engages against the portion is of the shoe blank that projects beyond the toe, whereby when the said cli former 23 is moved forward by the die bar it pressesthe said portion is of the blank into the recess m of the operating table 10. y The clip X is formed upon the toe of the shoe by this operation. The said clip former 23 is held in a horizontal position by. the supporting bars 21 and 22 which are pivotally mounted upon the studs 26 and 27 and are adapted to be swung under the said clip former, as shown in Fig. 4, for the purpose as before stated of holding the clip former in opera- "of the blank being still sufficiently heated to admit of the same being readily pressed into the form of the clip by the former.

'Having described my invention, What I claim and desire to secure .by Letters Patent is:

- 1. In a machine for forming the heels and toes upon horse shoes, the combination of a frame, means to hold'the blank shoe in operative position, means to convey an electric current to and localize the same at the heels and toes so" as to produce a welding temperature at said points, and means to press the heated shoe and calk sufiiciently to Weld the same, and means to turn the ends of the blank at right angles to form the heels.

2. In an apparatus for forming the heels and toes upon horse shoes, the combination of a frame, acam mounted in said frame, a die-bar actuated by said cam, a blank holder secured in said frame and adapted to hold the blank shoe in position during the-operation, a cam adapted to press the ends of the blank horseshoe, at right angles to the length thereof, and means to convey a cur rent and localize the same at the heels and toes of said blank shoe for the purpose of making suflicient heat to produce a welding temperature therein as described.

3. In a machine for forming the toes upon the heated portion of the blank shoe to form horseshoes, the combination of a frame, means for holding a blank shoe in operative position upon the 'frame,.means. for heating a portion of the shoe blank to a Welding temperature, a die bar mounted 'upon the frame for forcing a calk against the heated portion of the shoe blank to weld the calk in position thereon, and means upon the die bar for acting upon the heatedportion of the shoe blank to form a clip thereon.

4:. In a machine for producing horseshoes, the combination of a frame, means for holding a blank shoe in operative position there- 011, means for heating a portion of the blank shoe to a weldingtempera'ture, a die bar mounted upon the frame, means cooperating with the die bar to force a calk member against the heated portion of the blank shoe, a clip former movably mounted upon the die bar, and means for retaining the clip former in operative position, the clip former serving to act upon the heated portion of the blank shoe to form a clip thereon.

5. In an apparatus for producing horse- 1 shoes, the combination of a frame, means for holding a blank shoe in operative position upon the frame, means for heating a portion of the blank shoe to a Welding temperature, a die bar, means cooperating with the die bar to force a calk memberagainst the heated portion of the blank shoe, a clip former pivotally mounted upon the die bar and adapted to be swung into an inoperative position, and means for holding the clip former in an operative position,"the said clip former being adapted to act upon a clip thereon. v In testimony whereof, I have hereunto signed my name in the presence of two subscribing 'witnesses.
